6 Specifications and Characteristics
100 U3402A User’s and Service Guide
• Response time
• Approximately 1.5 seconds when the displayed reading reaches 99.9% AC RMS value of the
tested input signal at the same range.
AC voltage (True RMS AC + DC Coupling Mode)
• Measurement method
• AC+DC coupled true RMS—measure the AC component with up to 400 VDC bias on any
range
• Crest factor
• Maximum 3:0 at full scale
• Input impedance
• 1 MW ± 2% in parallel with <120 pF of all ranges
• Maximum input voltage
• 750 V RMS /1100 V PEAK
• 2x10
7
V-Hz product on any range, normal mode input
• 1x10
6
V-Hz product on any range, common mode input
• Overload ranging
• Will select higher range if peak input overload is detected during autorange. Overload is
reported in manual ranging
• Input protection
• 750 V RMS on all ranges
• Response time
• Approximately 2.5 seconds when the displayed reading reaches 99.9% AC RMS value of the
tested input signal at the same range
